Genetic indicators
COI — inbreeding
2.54%
Low. Common ancestors: Kouji Go Serikawa, Toyobenime (Toyobenihime?) Go Nidai Maneisou, Hamajiro Go Toyohama Unryusow.
AVK — distinct ancestors
85.5%
53 distinct ancestors out of 62 possible. Among known ancestors only: 88.3%.
Pedigree completeness
96.8%
2 empty slots. The AVK takes them into account, so read both figures together.
Value for the breed's diversity
Rare pedigree — rarer than 96% of the Shiba born in the last 15 years (since 2012)
How often its ancestors (over 6 generations) appear in the pedigrees of the 11,572 recent dogs: using dogs with a rare pedigree helps keep diversity in the breed. Over: 6 generations 8 generations 10 generations
Common ancestors and how they connect 3
Over 5 generations: each ancestor found on both the sire's and the dam's side, and what it adds to the COI.
| Ancestor | Sire's side | Dam's side | Share of the COI |
|---|---|---|---|
| Kouji Go Serikawa ♂ | gen. 3 | gen. 4 | 1.56% |
| Toyobenime (Toyobenihime?) Go Nidai Maneisou ♀ | gen. 4 | gen. 4 | 0.78% |
| Hamajiro Go Toyohama Unryusow ♂ | gen. 5 ×2 | gen. 5 | 0.2% |
| COI over 5 generations | 2.54% | ||
How the lines connect
Only the dogs that lead to a common ancestor are drawn. Each coloured line goes from a common ancestor down to its descendants. Click a dog to open its page.

How these figures are calculated
COI — Wright's formula: F = Σ (½)n₁+n₂+1 × (1 + FA), summed over every path through a common ancestor A. The number of generations must be fixed for two dogs to be comparable: a more complete pedigree mechanically raises the figure.
AVK — distinct ancestors divided by the theoretical number of ancestors. Over 5 generations there are 62 possible slots. 100% means no ancestor appears twice.
Completeness — the share of slots actually filled in. The AVK is misleading without it: a half-empty pedigree shows a low AVK even with no inbreeding at all, simply because data is missing.
